Material Notes:
Fibermax Mat is a high-temperature, flexible mat product that is lightweight (1.5 lb/ft3 density) and highly resilient. It is composed entirely of Fibermax polycrystalline mullite fibers to produce a product that is high-temperaure (1650°C / 3000°F) resistant and virtually shot-free.Fibermax Mat contains no organic binders or other additives which cause outgassing fumes or associated problems. In addition to exhibiting excellent resistance to attack from most corrosive agents (exceptions include hydrofluoric acid, phosphoric acid and strong alkalies), Fibermax fiber also resists oxidation and reduction.Typical ApplicationsExpansion joint packingBurner wrapsBatten strips with fiber modulesAluminum homogenizing furnace liningsInformation Provided by Unifrax I LLC
